Bought this over the summer with the intention of using it mainly at the beach to dig "bathtubs" for my kids. I love how portable and lightweight it is, while also providing plenty of heft and just a sturdy feeling in your hands.
However, I've found the sand and saltwater probably aren't the best for this shovel, though repeatedly oiling it does help.
Nevertheless, I'll still give this 5 stars as sandy beaches aren't exactly what this tool was built for and yet it is still standing up to this job.
I have this strapped to the rack of my ATV. It works great to get the tires out of the suction of deep mud when I get stuck. Serrated edge needed some sharpening to be useful but that was easy. After it is unfolded and the fasteners are secured, it makes a very nice and solid shovel.
I bought this product about two months ago. It works amazingly. The only thing I had to do outside of the box was tighten the bolts because the bolts were a little loose. The saw is also not so good. I filed down the saw to make it sharper.
